After the player catches both of them, return to the shrine with both Tornadus and Thundurus in party. The Trio Master Landorus will then be seen waiting for the player. Rather than fleeing, it will instantly battle the player, serving as the only Pokémon battle in this place and making a reference to how Landorus is found at Abundant Shrine, Unova in Pokémon Black and White.

So, you have to spend 100 hours looking for Thundurus and Tornadus you can finally get Landorus?
